    Undergrad Radioactive decay of Carbon 14

    Alright, a very simple question here. I am reading about nuclear decay of Carbon 14 into Nitrogen 14. I understand how one electron is released and subsequently one neutron turns into a proton, but I am curious about how many electrons are left with the Nitrogen atom. I want to believe five, as...

    Showing the solution of an Euler DE oscillates

    Homework Statement I have the DE which is an Euler DE. Show that if k >1/4, the solution of the DE would oscillate. Homework Equations eix= cos(x) +isin(x) I assume. The Attempt at a Solution I understand here that if k>1/4 the solution of the DE may oscillate, but if k1/4, it will not. I...

    Finding the accuracy of an approximated potential

    Homework Statement Charges +/- q separated by a distance d make a dipole with dipole moment qd. For large r the potential approaches qdcosθ/(4πε0r²). For θ=0, how large must r be so that the asymptotic function is accurate to 1%? Homework Equations Exact V= q1/(4πε0r) + q2 /(4πε0r) Approximate...
